I made mine with a camp I helped out for elementary school students in mind - I put meal related things on top, social-related on the right, and adult related on the left. But this would be great to adapt to your own personal needs, too! You can use picture symbols instead of words for non-readers and use vocabulary more common at home. If I had to go back, I'd add in "like", "dislike", "I", and "want" that way you can prompt for sentence production (ie the child can point to "I want food").
Let me know what you would do to yours! You can buy them online but I literally drew this one in five minutes in class and all you'd need to do is laminate it.
